14 Claims.

The primary object and main purpose of the machine here illustrated is to increase the firmness of attachment to an innersole body of an originally separate rib strip which has already been connected by adhesive to such a body. An associated object is to compress and consolidate the rib and give it a desired inclination to the plane of the innersole. With these objects in view the essentials of the invention comprise l complemen'tal instruments, preferably in the form of rolls cooperatively arranged and driven to apply pressure to the rib and its parts, and at the same time to feed the ribbed innersole with progressive application of pressure lengthwise of the rib.

Although the objects of the invention are pri marily those above stated, nevertheless such statement is not to be construed as limiting the utility of the invention or the scope of protecm tion claimed for it; since we claim all novel principles and characteristics of the machine for all purposes to which they may be usefully applied.

The drawings furnished herewith show a machine embodying the principles of the invention in the form, arrangement and structure at present preferred to others.

Like reference characters designate the same parts wherever they occur in all the figures.

The base ll of the machine is provided with legs adapted to rest on a bench or other suitable support, and has a flat upper surface to sup- 5 port the work while passing the operating tools.

Such tools comprise a double conical roll I2, a second double conical roll !3, and a cylindrical roll M. In the preferred construction, here shown, the roll i2 is secured to a shaft l5 which rotates in bearings it and H, but has no other motion either axially .or laterally. Bearing H5 is formed in the rear Wall of the base and bearing ii is formed in an arm is which rises from the top of the base in rear of the space in which the work is placed and fed while being acted upon. Arm l8 extends in a curve upwardly and forwardly to a termination above and clear of the base, and at its extremity is formed with a bore or passage in which is fixed an upright I pivot pin 89.

Roll i3 is secured to the lower extremity of a shaft 251 which is both rotatable and movable endwise in separated bearings 2i and 22 in a carrier 23 which is pivotally supported by means of the arm 58 and pivot Hi; the carrier having separated eyes 25 at its end remote from that in which shaft 26 is held, which eyes embrace the extremity of arm l8 and receive the ends of pivat 59. Shaft 26 is pressed endwise downwardly by a spring 25 surrounding, and pressing against a collar 28 secured to, the shaft. This spring reacts against the hearing 2! through an interposed ball thrust bearing 21, being confined under tension between the latter and collar 26. The downward movement of this shaft is limited by a belt pulley 28 secured to the shaft adjacent to the upper and outer end of bearing 2!. Spring 25 thus causes roll 13 to exert downward pressure on work engaged with the subjacent supporting cylindrical roll l4, and permits roll 53 to yield upwardly when a work piece is inserted, and to accommodate different thicknesses of work.

Roll 63 is movable away from roll l2 by virtue of its pivotal support, previously described. It is yieldingly pressed toward roll [2 by a spring 29 (Fig. 2) which presses against an arm 3% protruding from the side of bearing 22. This spring surrounds a rod 3| which passes freely through an opening in arm 30 and is securely anchored in a fixed arm 32 projecting from the side of the stationary shaft bearing ll. Rod 3! extends forwardly from the arm 3% and has ahead 33 between which and arm ,30 the spring 2% is confined under compression.

Roll M is spring pressed upwardly to support the sole being operated on and press it against the cooperating rolls l2 and I3. Its upper side or limb protrudes through an opening in the top surface of the base. It is secured to a shaft 3 having rotative'bearing in the opposite side members of a frame 35 which is connected by a pivot 3% to legs 31 underneath the base, and is yieldingly pressed upwardly by a spring 38. This spring surrounds the shank of a screw 39, which passes freely through an eye 40 in the free end of the frame 35 and is screwed into a boss M on the under side of the top surface of the base. Spring 38 is confined between the head on the lower end of screw 39 and the eye 2-3. Boss l! establishes the upper limit to which the roll i l may be moved by the spring.

Rolls i2 and iii are independently driven from a countershaft 3 mounted in a bearing M5 at 5 one end of the base. This countershaft is driven by a pulley 5E and belt 56. It carries two other pulleys ll and :38; the former of which drives by means of belt a pulley 59 on the outer extremity of shaft l5, while pulley i8 drives by a belt 5| 10 the pulley 28 previously described as being secured to roll shaft 20. Shaft 34 of roll It, is driven from shaft i5 by bevel gears 52 and 53.

As shown, the axes of all the rolls are in the same plane; and the rolls are so related to one another in this plane that the rolls i2 and 13 are adapted to grip between them the rib a of an innersole I), while at the same time these two rolls cooperate with roll it in pressing the flanges e, (Z of such rib against the surface of the sole. The springs acting on rolls i3 and M as described permit these rolls to separate from each other and from the nonyielding roll l2 when a sole, with lightly attached rib, is passed between them in the manner shown in Figs. 3 and 4, and cause them to press firmly, and with pressure limited only by the strength of the springs, in the directions necessary to insure firm contact of the rib flanges with the sole and compacting of the rib itself. The rim or ridge between the opposed conical faces of each of the rolls I2 and i3 is preferably made sharp or fine enough to enter fully into the corresponding contiguous angle between the rib and its adjacent base flange, making a well defined angle in the work, and, in particular, insuring a close contact directly at the base of the rib with the sole. In fact the angles of the conical faces may be so disposed as to concentrate the pressure at these rims or ridges if desired. But at the same time they are not so sharp as to cut the material of which the rib is made.

The face i2a of roll !2 and lSa of roll i3, that is the conical faces which grip the rib between them, are preferably fluted in order to secure a firm enough grip to feed the work steadily and smoothly. These faces in their intersections with the common axial plane may be parallel to one another, or somewhat convergent or divergent if desired; and may be perpendicular or inclined to the contiguous face of roll M, as needed either to set the rib upright with respect to the plane of the sole, or at any desired inclination. Also the faces i217 and iib of these rolls may be parallel to the surface of the roll it in the axial plane, if desired to exert an even pressure throughout the entire width of the base flanges e and d; or they may be at acute angles to the roll it if it is desired to concentrate the pressure in the angles between the rib and its flanges. These effects are obtainable within a considerable range of values of the angles made by the roll aXes with one another and of angles made by the conical faces with the respective axes of the rolls. Substantially, the shafts i5 and 29 are at acute angles to the shaft M, and at nearly right angles with one another; although considerable variation in the angle between the shafts E5 and 26 may be made from that shown without departing from the principles of the invention.

In the operation of the machine for the purpose herein described, an innersole to which a rib has first been attached by adhesive is introduced in the manner shown in Fig. 4. One end of the rib is placed in the nip of the rolls i2 and i3 75 while the sole itself and the flanges of the rib are brought between these rolls and the under roll M. Rotation of the rolls by the driving means described feeds the sole by the tractive effect of all the rolls, and pressure is thus progressively applied to all points in the length of the rib.

A guide or gauge roll 55 is mounted on the upper face of the machine base by an adjustable bracket 56 so as to bear on the edge of the sole at a point back of the pressure rolls to insure starting of the work in the right direction. A guide finger 5'? is secured to the arm 32 previously mentioned and projects partly around and under the roll l2 toward the gripping point, in position to enter the outer angle and engage the outer side of the rib, preventing the rib from being crushed be-- tween rolls l2 and it. With the assistance of such guides, the rolls are able to feed the work without assistance by the operator after the work piece has once been placed in the machine as described. The driving means (belt pulleys and gearing) are designed of such values as to give substantially equal peripheral speeds to the largest circumferences of all three rolls.

For convenience in distinguishing the rolls from one another by name, the roll i4 may be called the backing or reaction roll, the roll it. may be called the outer rib-engaging roll, and roll 63 may be called the inner rib-engaging roll.

In this illustration the rib is shown as composed of a folded strip of fabric with a stiffening core or strip within the central fold which forms the rib proper. And it is to be understood that the strip thus folded is ordinarily coated on one side with an adhesive of any suitable kind before being folded and placed on the surface of the body. It is to be understood, however, that ribbed innersoles otherwise constructed may be operated on by the machine; and also that the machine may be put to any other useful purpose for which it is adapted. Hence the title used as a convenient designation in this specification and in the following claims is to be construed simply as such and without limiting implications.
